Who We Are

The ORNL DAAC is a data center in NASA's Earth Observing System Data and Information System (EOSDIS).

Mission Statement and Goals

The mission of the ORNL DAAC is to assemble, distribute, and provide data services for a comprehensive archive of terrestrial biogeochemistry and ecological dynamics observations and models to facilitate research, education, and decision-making in support of NASA's Earth Science.

ORNL DAAC Data and Data Services are used to:

  • Understand terrestrial biogeochemical processes
  • Assess the accuracy and uncertainty of remote sensing products
  • Integrate process understanding within remote sensing observations
  • Develop, assess, and drive biogeochemical models
  • Educate future earth scientists
  • Provide information for decision-making activities

ORNL DAAC's Goals are to:

  • Serve as the primary active archive for biogeochemical dynamics data derived from NASA's field campaigns
  • Provide field data to assess the accuracy and uncertainty of NASA's remote sensing products
  • Work with NASA to develop best practices, tools, and training for data providers to generate terrestrial ecology and biogeochemical dynamics data for sharing and archival
  • Archive and disseminate regional and global data products for modeling and analysis
  • Archive and disseminate model source code to enable synthesis of results across modeling studies
  • Work with NASA to develop and use the best available technology to organize and present data to users
  • Facilitate interdisciplinary synthesis by providing and integrating diverse data required to address common hypothesis (across multiple scales, model-data intercomparison, etc.)

User Working Group

The ORNL DAAC User Working Group (UWG) provides guidance in defining and accomplishing the DAAC's science goals.
